The Furukawa Electric Co., Ltd. and Furukawa Techno Material Co., Ltd. (Headquarters: Hiratsuka-shi, Kanagawa-ken; President: Nobuyuki Nakamura; Capital: 300 million yen, 100% funded by Furukawa Electric) have additionally acquired accreditation PS060WL-0318 (for walls including hollow walls) and PS060FL-0319 (for floors) from the Minister of Land, Infrastructure and Transportation for the companies’ fire protection kit for compartment penetrations “Ichijikan-Fire Protection Pack”, which is applicable to heat insulation-covered metal or synthetic resin pipes, flexible electric conduits made of synthetic resin, as well as to cold- and hot-water supply sheathing pipes.
Through this additional accreditation, the Ichijikan-Fire Protection Pack can be used in various facilities piping having a nominal diameter of up to 100 including rigid polyvinyl chloride pipes in the electric, air-conditioning and sanitary fields. The sales amount is targeted at 300 million yen per year in combination with the scope of application conventionally accredited.
Conventional Problems and Their Solutions
The Building Standard Law of Japan requires that all piping systems should be provided with fire spread prevention measures having a predetermined performance level to achieve a fire resistive period of 1 hour maximum, when they penetrate walls and floors of fire-proof compartments in buildings.
The acquisition of additional accreditation this time has resolved the problems presented by the conventional products as listed below.
| Conventional problems | Solution by this product | |
|---|---|---|
| 1. | The use of this method was limited to small-diameter piping of heat insulation-covered metal pipes, sheathing pipes, and flexible electric conduits made of synthetic resin having a nominal diameter of up to 25 (or 45 in case of metal pipes). | The additional accreditation this time expandsthe applicability to large-diameter piping of eleven types in total. This product is applicable to every air-conditioning, supply- and drain-water, and electric piping, enabling unification of fire protection materials. |
| 2. | Conventionally, when rigid polyvinyl chloride pipes were used for draining in particular, the mortar filling method was mainly used, requiring tremendous labor. | Fire protection measures are completed simply by filling the filler pack into penetrations, saving labor due to this mortar-free method. |
| 3. | Mortar filling work needed not only complex labor but also a work hour of 30 min per spot, leading to possible delays in large-scale works. | A simple mortar-free work method has been realized, cutting the work hour to five min per spot. As a result, work period has been greatly reduced. |
| 4. | New fire resistant materials for penetrations were needed to enable renewal of the piping. | Use of this mortar-free method ensures ease of piping renewal. |
Scope of Application
The fire-proof and semi fire-proof walls (including hollow walls) and floors (of steel-reinforced concrete or ALC panel) accredited by the Minister of Land, Infrastructure and Transportation having a thickness of 80 mm and 100 mm, respectively.
Features of Ichijikan-Fire Protection Pack
- Installation is completed simply by filling a suitable-sized packing material, thus reducing the work period.
- At fire breaking, the heat-expanding material promptly blocks up the open space created by fused piping and the like.
- A single package contains all the materials needed for every installation spot.
- Applicable to openings with diameters of φ50~φ160.
